High Elasticity Marine Donut Fender For Protection And Guidance

Donut Fender

Donut fender is suitable for the places like lock entrances, turning 

structures, approach channels and breasting dolphins. It's often installed 

the surface of the quay wall and it can rise and fall with the tide. Apart from 

the feature of tide adaptation, Jerryborg donut fender can also rotate 

around the pile helping guiding vessels due to its low friction. 

Donut fender shares the same high-quality raw material and similar 

structure with foam filled fender, and it's unsinkable, easy to replace and 

maintain. Jerryborg can offer various donut fenders in different sizes and 

colors upon customer's request.   

Donut Fender Installation

The installation of donut fender is very simple. All we have to do is to deliver the fenders to the site and lift over and lower them onto the fender pile. We 

don't need to ballast or trim the fenders cause they'll float at the level that is already designed. The last step is to place the capping part over the top of 

the fender pile. Jerryborg offers the donut fenders with various sizes and colors with a long lifespan, besides they're cost-effective and easy to maintain.
